6 Claims. (Cl. 30--29".5)

rllhis invention relatesl to an improvement in hair cutting instruments and deals particularly with an apparatus for clipping hair in confined areas such as in the nostrils, ears or the like. The practice of. removing hair which grows in the nostrils can be dangerous if improperly done. The nostrils and ears are delicate parts of the human body and infection can easily occur from a cut resulting from using scissors for cutting the hair or may actually result from pulling out the hair. The present instrument is designed to accomplish the result in a simple and effective manner.

Certain devices have been produced for accomplishing a similar purpose. However, in most cases with which I am familiar, the clippers have been operated by a trigger movement or by some other type of hand movement which must be initiated while the clippers are in place. As a result it is difficult to support the clipper in the proper position and then manipulate the mechanism for rotating the head of the device. It is an object of this invention to obviate these previous difficulties.

A feature of the present invention resides in the provision of a hair clipping device which includes a rotat able clipper head rotatably supported to cooperate with lixed clipper fingers. The rotatable member is freely rotatable and can be turned with equal ease in either direction. Connected to the rotatable head to rotate in unison therewith is a fly wheel or weighted roller which creates sufficient momentum to maintain the rotatable member in rotation for a short period of time once it has been started. Accordingly, by starting the rotatable member in operation the ily wheel will maintain the clipper head in rotation until the head of the device is carefully guided into hair cutting position.

A feature of the present invention resides in the simplicity of the construction. The device includes but a small number of parts. The essential elements are the xed clipper member, the rotatable clipper member, and the ily wheel connected to the rotatable member. The form of construction and the handle arrangement is simple and the particular form may be changed.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification `and claims.

ln the drawings forming a part of the specification:

Figure 1 is a perspective view of a hair clipping apparatus showing the construction thereof.

Figure 2 is an elevation view of the clipper head showing the parts thereof.

Figure 3 is a sectional View through the apparatus showing the arrangement of parts therein.

Figure 4 is a top View through line 4 4 of Figure 2.

The hair clipping device is extremely simple in form and includes a handle member comprising a tubular body having integral therewith or attached thereto a head 11. The head 11 comprises a sleevelike body which is usually tapered upwardly and inwardly at its extremity as indicated at 12. The upper extremity of the sleeve is notched to provide a Series of angularly spaced teeth 13.- which form cutter teeth. The teethl 13 are provided with beveled edges` 12' to. aid in guiding the hairsl over the cutting edges 11. As the teeth 13 are stationary, they protect the4 surface of the skin from.l injury by the innerl rotatable cutter rnember'uvhichy will be presently described. The outermost ends of teeth '13- arel rounded as indicated at 13" and project slightly.k above thev inner rotatable cutting member to'- provide protection against abrasion and cutting' of the. flesh.

The lower endof the handleV 1:0 is connectedi by' one or more. bridging: members: 14. In the particular arrange ment' illustrated these bridging members compriseA strapsV which are bent into lli-shapedy form with the: armsf of the U extending horizontally one above the other. The inner endl of thei upper arm isconnected@ to asleeve 15 which encirclesY the lower end of the handle 10 and. is secured thereto by any suitable means@ suchi as thel screws- 16. 'Ehe lower end of each: bridge member is connected toa similarl sleeve 1:7 encircling a lower handle member 19. The sleeve 17 is secured to the lower handle member 19 by screws 20 or other suitable means.

The sleeve 15 is arranged to accommodate bearings 21 of any suitable type, these bearings being held from endwise movement when in position. The upper bearing 21 is held between the inwardly extending extremities 22 of the bridging members 14 and the lower end of the handle 10. The lower bearing 23 is held between the inner extremities 24 of the lower portion of the bridging members 14 and the upper end of the lower handle section 19.

A shaft 25 extends through the handle member 10 and the bearings 21 and 23 terminating in a socket 26 in the lower handle member 19. A ily wheel 2.7 of any suitable shape is mounted upon the shaft 25 between the bearings 21 and 23, this ily wheel being bridged or partially encircled by the bridging means 14. While in the form illustrated the bridging members are spaced and separate, it is obvious that this part may comprise a housing which encircles any desired amount of the ily wheel 27, leaving a suflicient opening so that the y wheel can be rotated.

The upper end of the shaft 25 is supported by a bearing 29 within the head 11 and the shaft is connected to a generally cup-shaped clipper head 30 which is rotatably supported within the head or shell 11. The upper end of the clipper head 30 is notched to provide angular-ly spaced teeth 31 as is indicated in the drawings. The teeth 31 are inset from the outermost ends of teeth 13. Thus the rounded ends 13 serve to abut against the tender flesh of the nostril, ears or the like and protect the esh against rupture o1' abra-sion.

The operation of the device is believed quite obvious from the foregoing description. When it is desired to use the clipping device, the fly wheel 27 is started into rotation by the thumbor linger and attains a reasonable speed. The clipper is then inserted into the nostril or into hair clipping position, the ily wheel maintaining the cutting head in rotation and permitting the clipping of hairs entering the notched upper end of the device.

In accordance with the patent statutes, I have described the principles of construction and operation of my hair cutting instrument, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.

I claim:

1. A linger operated hair clipper including a rotatable clipper head freely rotatable by a finger in either direction, a tubular handle supporting said head, a shaft connected to said head to rotate in unison therewith, and a weighted y wheel on said shaft for turning in either direction by frictional engagement of a finger therewith and maintaining the shaft and head in rotation for a period of time after it has been started in rotation.

. 2. The construction described in claim 1 and in which the head is in cooperable relation with a fixed cutter head.

3. A hair cutting device operable by frictional nger engagement including in combination a hair clipping head including a fixed member and a movable member, a rotatable shaft, a handle section supporting said shaft and said head, further means cooperable with said shaft and said movable member for supporting said member upon rotation of said shaft, and a y wheel on said shaft and rotatable therewith mounted between said handle sections with the periphery thereof exposed to be turned in either direction by frictional engagement of the fingers thereon.

4. The construction described in claim 3 and including cooperable cutting teeth in said fixed member and said movable member.

5. A finger friction operating hair clipping apparatus including a handle having a cup-shaped head thereupon,

Cil

a cooperable cup-shaped head rotatably supported within said first mentioned head, a shaft connected to said rotatable head and extending through said handle, and a y wheel on said shaft and rotatable therewith in either direction by fctional engagement of the fingers with the said fly wheel.

6. The construction described in claim 5 and including a handle extension and y wheel bridging means connecting said handle and said handle extension.
